We are seeking a back-end leaning Senior Developer to join our Growth Team, focused on building net-new self-serve experiences, evolving the underlying systems and integrations that power Product Growth, and driving rapid experimentation and feedback loops across our expanding B2B product suites. How we’re using AI today Our Engineering, Product, and Design teams are thoughtfully integrating AI across the full software and product development lifecycle to move faster without sacrificing quality or security. In practice, that looks like engineers using AI-assisted coding tools to accelerate reviews and catch bugs earlier, product managers synthesizing user research at scale, and designers rapidly prototyping and iterating with AI-generated mockups. We approach AI the same way we approach security: with clear principles, human accountability at every consequential decision point, and rigorous evaluation before anything ships to customers.

What you can expect: • Shape and evolve our experimentation platform (feature flags, instrumentation, data quality, reporting loops). • Lead the design and implementation of experiments that drive activation, engagement, and expansion. • Partner closely with product, design, and data to refine hypotheses, define measurable outcomes, and interpret results. • Balance rapid iteration with long-term architectural health and security. • Raise the bar for code quality, observability, and performance across the team. • Mentor engineers through code reviews, technical design discussions, and pairing. • Identify technical op
